The RE+ 2025 conference in Las Vegas was a clear reflection of where the renewable energy market is heading. Battery storage is becoming the centerpiece of many energy strategies.
As Premier Transformer walked the floor, met with developers, integrators, and EPC firms, and evaluated the shifting focus across the industry, one trend stood out above the rest: battery energy storage systems (BESS) are rapidly dominating the conversation.
The Rise of Battery Storage Systems
Battery developers and integrators had a significant presence at RE+, showcasing innovations across lithium-ion, flow, and emerging chemistries. What used to be considered an auxiliary component of solar or wind installations is now viewed as essential grid infrastructure in its own right.
This momentum is being driven by a greater focus on grid resilience and reliability, increased demand for dispatchable, on-demand renewable energy, shorter lead times and cost improvements in BESS technologies, and strong interest and investment from international companies entering the U.S. market.
Across nearly every booth and conversation, it was clear that battery storage is not the future, it’s the present.
Where Premier Transformer Fits
Power electronics and transformers are critical components in the design and performance of battery energy storage systems. At Premier Transformer, we’ve long supported BESS projects with transformers designed specifically for:
- Bidirectional power flow
- High-efficiency under variable load conditions
- Custom voltage configurations (e.g., 34.5 kV – 600V, 12.47 kV – 480V, etc.)
- Compact footprints for containerized or space-limited applications
- Advanced monitoring and protection systems
Whether it’s utility-scale storage co-located with renewables or standalone BESS installations supporting grid peak shaving and frequency regulation, our team engineers and delivers customized, UL-compliant, and high-performance transformers with industry-leading lead times.
International Activity in a Fast-Moving Market
Another major observation from RE+ was the number of international companies entering the battery storage and grid infrastructure space. This expanding field means faster innovation and greater competition and complexity for EPCs, developers, and utilities sourcing critical equipment.
With over 45 years of manufacturing excellence, and active U.S. operations, Premier Transformer offers the best of both worlds: global manufacturing capability and localized support. We deliver quickly, meet U.S. standards, and understand the challenges BESS projects face in today’s regulatory and development landscape.
Battery Storage Is the Moment, and We’re Built for It
RE+ 2025 made it clear that battery energy storage is where the energy industry is investing its attention, resources, and innovation. As developers look for responsive, reliable partners who can deliver high-quality transformers designed for these projects, Premier Transformer is ready.
Whether you’re working on your next BESS deployment or need support designing a substation or pad-mount solution to support grid-scale storage, our team is here to help.
